How can the doffing of cotton spinning end quickly and break less?

It is estimated that you are 30% yarn, and it is an old machine that has been used for a long time! In fact, it is not easy to break! There is a thread after the left-hand yarn is taken out, so try to keep a little more spinning and take it directly from the machine. Put the pipe down gently, it's easy to break that line directly! After finishing a doffing action, gently hook the yarn with your fingers, if it is easy to hook it out. Then you failed. Repeat several times to find the feeling. You should start at once!
